Businesses received 427 million malicious emails in 2024

In 2024, businesses received over 20.5 billion emails, with 36.9% classified as unwanted. Of these, 427.8 million contained malicious content, highlighting a significant rise in cyber threats, particularly phishing attacks, which accounted for one-third of all incidents. New tactics, such as reverse proxy credential theft, have emerged, allowing hackers to bypass two-factor authentication by redirecting users to fake login pages. Malicious URLs now make up 22.7% of cyberattack strategies, reflecting a notable increase from 2023. Despite a decline in the overall threat index for most industries, targeted attacks remain prevalent, especially in mining, entertainment, and manufacturing. Organizations are urged to enhance email filtering, adopt multi-layered authentication, and prioritize employee training to combat these evolving threats.
